$60.00
About this product
The KWI Silver/Purple Primary Spring is a purpose-built engagement spring for KWI UltraShift clutch systems — calibrated for a 2,200–2,400 RPM engagement range. Available individually for riders dialing in their UltraShift setup or replacing a worn spring without purchasing a full kit.
The 2,200–2,400 RPM engagement window makes this spring the mid-range option in the UltraShift spring lineup — delivering smooth, predictable clutch engagement for a wide range of riding conditions and power levels. If your current engagement RPM is too low or too high for your setup, swapping to the Silver/Purple Spring is the straightforward way to bring it back into the right range.
